Step‑by‑Step Instructions for Oogie Boogie Halloween Trifle
Step 1: Bake the Cake
Start by preparing the chocolate cake according to the package instructions, using a 9×13 inch baking dish. Preheat your oven to 350°F (175°C) and bake for around 30-35 minutes or until a toothpick inserted emerges clean. Once baked, allow the cake to cool completely, then cut it into bite-sized cubes for layering in the Oogie Boogie Halloween Trifle.
Step 2: Prepare the Mousse
In a large mixing bowl, combine the white chocolate pudding mix and 2 cups of cold 2% milk. Whisk vigorously for about 2 minutes until the mixture begins to thicken. Next, gently fold in 1 tub of thawed Cool Whip until fully combined, ensuring the mousse is light and airy. To achieve that iconic spooky green color, add a few drops of green food coloring and mix well until uniformly colored.
Step 3: Layer the Trifle
Grab your favorite clear trifle dish to beautifully display the layers of your Oogie Boogie Halloween Trifle. Start by placing a layer of the mousse mixture, roughly 1/4 of the total, at the bottom of the dish. Next, add a layer of one-third of the chocolate cake cubes followed by a third of the crushed Oreos. Finish this layer with playful gummy worms scattered throughout, adding a touch of fun.
Step 4: Repeat the Layers
Continue the layering process by repeating the mousse, cake, Oreos, and gummy worms until all components are used up. Aim for three complete layers, with the final layer being the mousse mixture on top. Make sure to evenly distribute the ingredients for a balanced trifle. It’s visually striking when you can see the vibrant colors and textures shine through the clear trifle dish.
Step 5: Garnish and Chill
To add the finishing touches to your Oogie Boogie Halloween Trifle, sprinkle the top with the remaining crushed Oreos and arrange more gummy worms for decoration. Cover the trifle dish with plastic wrap and place it in the refrigerator. Chill for at least 2 hours to allow the flavors to meld and the mousse to set, ensuring a delightful treat when it’s time to serve.
Step 6: Serve and Enjoy
When ready to serve, carefully remove the trifle from the refrigerator. Scoop out portions so that each slice showcases the luscious layers of green mousse, chocolate cake, and crunchy Oreos. This cheerful, no-bake Oogie Boogie Halloween Trifle is the perfect spooky dessert that will surely impress both kids and adults alike at your Halloween celebration!

Expert Tips for Oogie Boogie Halloween Trifle
